Am i having a latency issue?

Hello,

i am using a novation twitch with a MBP 4gb RAM, i7 processor with traktor 2.5 !

I am having trouble getting my latency anywhere near 10ms. My “load” meter in traktor dosen’t get red at all but i can still ear some audio glitches.

I think it is since i’ve upgraded to traktor 2.5.. or is it normal to have atleast (!) 15ms latency with a macbook pro and a twitch?

I don’t really know what to do, and i have a few gigs coming soon :s

Thank you ! :slight_smile:

What is the audio “glitch” you are hearing.. bleeps, cracks, stop in Audio? Im not a serato user so I am not sure how helpful I can be :confused:

Hello !

It never stops the audio, it is more like, if you pay attention, you notice that sometimes it tends to crack, a bit like old vinyl records !

Also, i am using traktor, not serato :slight_smile:

Hm, the ram might be filled with temp data from the library. Try creating a new library with only a couple songs and check back on the issue.
And no, 15ms isn’t normal afaik..

Thanks for the tip !

If i use only folders in traktor and traktor playlist, how do i do that ?

I wouldn’t know that, since i never used traktor extensively…
I’m thinking, it might even be your USB cable. Try changing it with another one and plug it into a different port, does it still have the same issue?
Also, is your mbp updated to 10.8.3?

Thanks, i’ll google that !

As for usb cable, i have a few tests !

And no, it is till at 10.7.5 ! I’ll need an update haha !

Thanks for the help, really, i’ll try that :slight_smile:

If i’m not mistaken, 10.7.5 had some USB dropout problems that were never fixed, and they were only fixed in 10.8 and higher.
I personally never had any usb cable problems, but i have some friends who had. Might me a manufacturing issue in the connector itself.
No problem, just ask if you need any further help :smiley:

heh.. Thats why OS’s design caching :stuck_out_tongue: I can bet some money his ram isnt filling up with “Temp data”. Even if it stored cue points of his library entirely in ram, I doubt it would use in conjunction with traktor more than 1 gb if that.

As the other poster suggested I would update your OS, try a different USB port, and a cable. (Im anti apple, so I cant suggest anything beyond that) as ive heard some combinations of OSX and Traktor versions dont play nicely.

Is Dashboard running? I also have heard that has caused issues for Traktor and some versions of OSX

I know, but i remember once it happened to me that i had serato lagging a lot after i dropped my laptop, and when i opened it up i saw one of the ram sticks had come off, and i only had 2gb available. The massive library i have saturated the ram and serato’s performance was affected. When i inserted the other stick in it started behaving normally.
That’s why i was suggesting that ram might be the problem here. Even though i do not know how traktor handles library caching.

Updating to mountain lion (10.8.3) cost 20 bucks, but i found out i don’t have the lastest traktor update (didn’t see 2.6.1 coming) so i’m going to check this out before upgrading to 10.8.3 :slight_smile:

I have dashboard running, i’m going to try to stop it too ! Thanks a lot for the help guys!!

That sounds like god awful software design… your biggest 6 min lossless audio file is going to be like 70 mb… what in the world is Serato using all that Ram to do.. Theres no reason to store anything but the loaded songs, and an audio buffer in RAM

13

Your library is not stored in RAM. Only tracks loaded onto decks will be stored in RAM.

14

I don’t know. I just know that putting the stick back in solved the problem…

15

I tell you, i know my library is not stored in ram, because it’s 35k+ songs. BUT i still had that problem and re-adding more ram solved it :slight_smile:

16

I might try it someday (even though now i have another computer and 2x4gb sticks, so i can’t replicate the 2gb situation from back then).

Serato itch I k ow would not play nice with my laptop but traktor did sorta switched out my t6400 for a x9100 and even clocking down to lower then the 6400 stock clock speed serato performs better. Also know wasn’t ram 8gb ddr3 or hard drives twin ssd make for little issues there.
